HENRY J. SCHULDT, OF ST. PAUL, MINNESOTA.

WINDOW GUARD.

Application filed January 17, 1923, Serial No. 613,315. Renewed January 9, 1925.

T all whom it may concern:

Be it known that I, HENRY J. SorIULDT, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Window Guards, of which the following is a specification.

My invention relates'rto window guards particularly adapted for use in windows of machine shops, hospitals, sanitariums and other places where window guards are used.

The objectis to provide a simple and efficient guard the use of which not only protects window lights but also, for example, prevents inmates of an institution from escaping, or burglars from entering abuilding. The windows equipped with my device are readily accessible, when so desired,

. by certain persons only, and other advantages are apparent from the following description and in the accompanying drawing, in which-- Fig. 1 is an inside elevation of a window frame equipped with my improved guard.

Fig. 2 is an enlarged sectional view as on line 2-2 in Fig.1.

Fig. 3 is a vertical sectional. view as on line 3-3 in Fig. 2.

Referring to the drawing by reference numerals, 4 designates the lintel, 5 the sill and 6 and 7 ,respectively, the left and right upright side pieces of awindow frame.

My improved guard. is a wired metal frame slightly smaller than. the window opening and hingedl'y'secured to one of the upright members and adapted to be locked to the other upright member; the inner side of the guard is preferably, when in locked position, about in a common vertical plane with the inner side of the said window frame.

The metal frame will ordinarily be made about as shown in Fig.1, 8 being the upper,

9 the middle and 10 the lower, horizontal bars, and 11 and 12, respectively,the left and right vertical bars, all. preferably of light channel iron and weldedor otherwise secured together to. form a rectangular frame slightly smaller than the window opening. The webs ofall the outside channels are inwardly disposed, andthe bar 9 may be composed of two channels placed.

flange to flange against each' other and riveted together as at 13.

Suitable wire netting 14 is stretched across the rectangular spaces between the channel bars, the ends of the wires being.

by a plate or flat bar 17 or 17, secured by rivets 18. The bar 17 is secured by hinges 19 to the upright 7' with or without spacing washers or strips 20 to make the guard fit window frames varying some 1n width. In

similar manner is secured to upright 6, by

screws 21, several hinges 22 each of which has one member formed with a hook 23 serving to limit the swinging of the guard toward the window (not shown). The other member 22 of each hinge is secured by rivets 24 to a flat vertical locking bar 25 which is thus arranged to be swung in front of the edge of the closed guard. Said bar 25 is provided with a. rigid arm or hasp 26 in which is fixed a staple 27 adapted to pass into an aperture 28 and be engaged by the bolt 29 of a suitable lock 30 fixed in the guard by a special frame 31an'd having a tumbler 32 operated bya removable key 33.

In the use of the device the guard is closed and locked at the inward side of the window and the key removed. When the guard is to be opened so as to reach the window to wash it or open or close it, the key is applied, the hasp 26 and bar 25 swung away from the gua-rdwhile the operator is at work, and

then closed again and the keyremoved.

What I claim is:

The combination with a window frame of a wire nettingguard covering the window opening, primary hinges holding one of the vertical edges of the guard to the frame,

secondary hinges secured in the frame 'opthe guard locked.

In testimony whereof I afiix my signature.

HENRY J. SGHULDT.
